What's New in TX Text Control .NET for WPF 21.0

Content controls of MS Word documents became programmable in TX Text Control 21.0 through a set of field adapters. The WPF TextControl also learned to detect the language of its text with TX Spell .NET, and its find and replace dialog boxes began to search the whole document.

Version 21.0 was released in September 2014 as TX Text Control X11, together with TX Spell .NET 5.0 and TX Barcode .NET 4.0, as the blog article TX Text Control X11 Released: Cross-browser Template Editing announced. The HTML5 Web Editor and the ServerVisualization namespace that the same version introduced belong to TX Text Control .NET Server and aren't listed here.

Version 21.0 at a Glance

Language Detection

With TX Spell .NET 5.0 connected, setting WPF.TextControl.IsLanguageDetectionEnabled to true detects the language of all text that has the neutral language. ServerTextControl.IsLanguageDetectionEnabled does the same without a user interface. See Spell Checking and Hyphenation.

Find and Replace

• The whole document. The built-in find and replace dialog boxes continue the search in text frames and in headers and footers instead of stopping at the end of the main text.
• Whole words. The FindOptions value MatchWholeWord finds only occurrences of the search text that are whole words.
• Localization. The Find, Replace and Color dialog boxes are part of the resource kit and can be translated. See Localization and Resource Kit.

Content Control Adapters

Content controls are the controls that MS Word adds to documents and templates to automate them. The DocumentServer.Fields namespace received an adapter class for each kind, so that you read and change them without editing the parameters of the underlying ApplicationField:

• Text. RichTextContentControl and PlainTextContentControl.
• Choices. CheckBoxContentControl, ComboBoxContentControl and DropDownListContentControl. The feature list of the version calls the last one "DropDownContentControl"; the class is named DropDownListContentControl.
• Dates. DateContentControl, with the calendar, the date format and the language of the date.
• Common properties. The base class ContentControlFieldAdapter provides Id, Tag, Title, Placeholder, ContentEditable, ContentDeletable and Type.

Fields and Subtext Parts describes the fields of MS Word documents and their adapter classes today.

Tables and Version Information

• Table ranges. A new overload of Table.Select selects the part of a table between two cells. See Tables and Calculations.
• Version information. WPF.TextControl.GetVersionInfo and ServerTextControl.GetVersionInfo return a VersionInfo object with the Major and Minor version, the ServicePack number (0 for the original release) and the product level. The reference documents the product level as the property ProductLevel, but in the assemblies the property is named Level, and ProductLevel is the type of its value.
